Administrator’s Capabilities 
Fine-tuning for Best Performance 
There are a few choices the Administrator is allowed to maximize the capabilities of 
the Network Camera.  Best performance generally equates to the fastest image 
refresh rate with the best video quality, and at the lowest network bandwidth as 
possible. The three factors, “Maximum frame rate”, “Fix bit rate”, and “Fix quality” on 
the Video Configuration page, are correlative to allow for achieving the best 
performance possible. 
 
 
For Best Real-time Video Images 
To achieve good real-time visual effect, the network bandwidth should be large 
enough to allow a transmission rate of greater than 20 image frames per second.    If 
the broadband network is over 1 Mbps, set the “Fix bit rate” to 1000Kbps or 
1200Kbps, or set “Fix quality” at the highest quality. The maximum frame rate is 25 
fps in a 50Hz system and 30 fps in a 60Hz system. If your network bandwidth is more
